We are a core and we have two ABI 373 sequencers.  We use the Prism kits
only. Investigators bring us their samples with primer in them and all we
do are the reactions and load.   The majority of the problems you will
incur will be the quality of the DNA.  People will get very frustrated as
samples that they will be able to sequence manually will give them garbage
on the automated sequencer.  It seems that Quiagen preps produce quality
DNA.  I think that you should have one person that does reactions and
loads the gel.  It would just seem chaotic with multi-users, and runs
would be done without the gel being fully loaded and that would be a waste
of 14 hrs.

Good Luck,
